WASHING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 245,917, dated August 16, 1881.

Application filed June 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV BURKHARDT, a citizen of the United States, residing at Homer, in the county of Ohampaign and State of Illinois, haveinvented new and useful Improvements in VVashing-Machines, of which the following is a specification.

This invention consists in a washing-niachine in which are combined a cylindrical base,

I0 a conical hood secured above the base by upwardlyprojecting arms, thereby creating an intervening space between the adjacent edges of the hood and the base, a conical perforated plunger beneath the hood, flap-valves arranged on the plunger opposite its perforations to close in an upward direction, a reciprocating plunger-rod guided in the hood, and a spring acting on the plunger-rod with a tendency to raise the plunger, so that if the whole is placed in a tub containing the clothes to be washed, with the lower edge of the base resting on the'clothes, a current of mixed air and water can be forced through the clothes by means of the plunger. Radial corrugated 2 5 rollers are applied to the plunger for pounding the clothes.

This invention is illustrated in the accompanying drawings, in which Figure 1 represents an inverted plan view. Fig. 2 is a vertical o cross-section on the line mm, Fig. 1. Fig. 3 is a similar section on the line y y, Fig. 1.

Similar letters indicate corresponding parts.

The letterAdesignates the base; B, the hood; 0, the plunger; D, the valves; E, the plunger- 5 rod; F, the spring, and G rollers or pounders.

The base A is cylindrical, and the hood B is secured thereto by vertical arms h, which project above the top edge of the base, where they are joined to the hood, thereby creating a space between the adjacent edges of the base and the hood. Both the hood B and the plunger (3 have an approximately conical shape, and the plunger is beneath the hood, itsnortnal position being within or directly beneath it. In

4 5 the plunger C are formed holes or perforations 7c, opposite to which are located the flap-valves D, these valves being hung on the inner or under surface of the plunger, as at Z, to close in an upward direction, and resting on staples n when open.

The plunger-rod E is guided in the hood B at the upper end of the hood, where the latter is provided with a tubular extension, 0, and the spring F is coiled on the rod, one end of the spring bearing against the hood and the other end against a sleeve, 1), fixed to the rod, so that the spring acts on the rod with a tendency to raise the plunger to its normal position.

The rollers G are corrugated respectively ina 6c longitudinal direction, and are mounted loosely .on radial shafts g, which are fixed to the plunger G at or near its lower edge, the shafts intersecting each other and being connected to gether by a central ring, 1. I

The clothes to be washed having been placed in a suitable tub with sufiicient water to saturate the clothes, the apparatus is placed into the tub with the lower edge of'ttie base A resting on the clothes, and then the plunger 0 is alternately depressed against the action of the spring F to bring it into contact with the clothes, and allowed to rise. In the descent of the plunger the valves D close and the plunger is filled with air, which is forced through 7 5 the clothes, together with the water, while in the ascent of the plunger the valves open, thus allowing or facilitating such motion. By the action of the plunger the rollers G are caused to pound or beat the clothes, thus loosening 8c the dirt.

What I claim as new, and desire to secure by Letters Patent, is

The combination, substantially as hereinbefore set forth, of the cylindrical base, the coni- 8 5 cal hood, the conical perforated plunger beneath the hood, the flap-valves arranged on the plunger opposite its perforations to close in an upward direction, the radial corrugated rollers or pounders of the plunger, the recip- 9o rocating plunger-rod, and the spring acting on the plunger-rod with a tendency to raise the plunger, as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two sub- 5 scribing witnesses.

GUSTAV BURKHARDT.
